SYNOPSIS

DESCRIPTION

xzcmp
and
xzdiff
invoke
cmp(1)
or
diff(1)
on files compressed with
xz(1),
lzma(1),
gzip(1),
bzip2(1),
or
lzop(1).
All options specified are passed directly to
cmp(1)
or
diff(1).
If only one file is specified, then the files compared are
file1
(which must have a suffix of a supported compression format) and
file1
from which the compression format suffix has been stripped.
If two files are specified,
then they are uncompressed if necessary and fed to
cmp(1)
or
diff(1).
The exit status from
cmp(1)
or
diff(1)
is preserved.

The names
lzcmp
and
lzdiff
are provided for backward compatibility with LZMA Utils.

BUGS

Messages from the
cmp(1)
or
diff(1)
programs refer to temporary filenames instead of those specified.
